Fig. 3 is the diagram of the operating process that capacitance-type touch-sensing method according to an embodiment of the invention is shown.
With reference to Fig. 3, first, touch-sensing control module 212, in step 310, judges whether touch panel 211 there occurs touch input.Next, in step 320, touch-sensing control module 212, judges whether the touch input occurred is the input undertaken by felt pen.In step 320, touch-sensing control module 212, when touching input and occurring, determines to touch input area.Touch the determination of input area, general watershed divide (watershed) algorithm can be used to perform.Next, touch-sensing control module 212, touches the peak response value of initial 2 frames of input area whether in the felt pen determination range preset when judging to touch input.Described felt pen determination range, can be set to 20% to 30% of the peak response value of the touch input area occurred when using general finger to carry out touching input.Such as, when using finger to carry out peak response value average out to 55 to 65 of the touch input area occurred in touch sensor when touching input, the scope of the felt pen size preset can be set to 10 to 20.
Fig. 4 illustrates to use the general example pointing each touch area touch sensitivity when carrying out touching input, and uses felt pen to carry out the diagram of the example touching each touch area touch sensitivity when inputting.In the ordinary course of things, use finger to perform and touch input, owing to there is wider contact area, so present the feature of the input area as shown in Fig. 4 (a).On the contrary, use felt pen to carry out touching input, owing to there is narrower contact area, therefore can present the feature of the input area as shown in Fig. 4 (b).
With reference to Fig. 4, as shown in Fig. 4 (a), use the peak response pointing the touch input area carried out to be 60, as shown in Fig. 4 (b), the peak response of the touch input area using felt pen to carry out is 13.In addition, use the peak response pointing the touch input area carried out, than using, the width pointing the touch input area carried out is little, the peak response of the touch input area using felt pen to carry out, larger than the width of the touch input area using felt pen to carry out.
The present invention utilizes such feature, for detecting the input using felt pen to carry out, judge whether the peak response value of the touch input area inputted is included in felt pen determination range, and judge whether the peak response value touching input area is greater than the width touching input area.
Fig. 5 illustrates the diagram using felt pen to carry out the formation example of the input area touched when inputting on touch panel, and uses general finger to carry out the diagram of the formation example of the input area touched when inputting on touch panel.In one embodiment of the invention, touch panel can comprise the array of multiple sensing electrode traces 501 and multiple drive electrode trace 502.In this situation, the interval between each electrode trace can be set as 4mm.In one embodiment of the invention, touch panel, the section sets that a sensing electrode trace 501 and drive electrode trace 502 can be intersected is a static capacity induction region.
Fig. 5 (a) shows the example of touch input area when touch panel of the present invention there occurs input by felt pen.When being inputted by felt pen, general contact area is that to be less than the situation of 2 π many, therefore, as shown in Fig. 5 (a), the input area 511 undertaken by pen is mostly detected in an only sensing electrode trace, and the touch input that size is similar can not be detected in multiple sensing electrode trace.
Fig. 5 (b) touches the example of input area when illustrating and use general finger to input on touch panel of the present invention.When there is input by finger, the contact area of general touch panel is that the situation of 4 more than π is more, therefore as shown in Fig. 5 (b), be formed on multiple sensing electrode trace by pointing the input area 521 carried out, therefore, the touch input that sensitivity is similar can be detected in the static capacity induction region 551,552 of adjacent sensing electrode trace.
As mentioned above, when input occurring by finger, the touch input that size is similar can be detected in contiguous static capacity induction region.But, when being inputted by felt pen, because contact area is less, the touch input that size is similar can not be detected in periphery static capacity induction region.Therefore, the present invention, when touch panel occurs input, judges whether there occurs the similar touch input of size in the static capacity induction region of the periphery of the static capacity induction region of peak response.Such as, the static capacity induction region of (upper and lower, left and right, upper left, lower-left, upper right, bottom right) on periphery 8 directions checking the static capacity induction region of maximum touch input sensitivity, judges whether to exist the static capacity induction region with the touch input sensitivity similar to maximum touch input sensitivity size.
Such as, when existence has the touch input sensitivity of periphery static capacity induction region of the touch input sensitivity of more than 80% of maximum touch input sensitivity, then the static capacity induction region of the touch input sensitivity that there is similar size is judged as.
Therefore, in step 320, touch-sensing control module 212, touch maximum input sensitivity periphery 8 directions that the peak response value of input area is included in felt pen determination range, to touch the peak response value of input area larger than the width touching input area, to touch input area do not exist size similar touch input sensitivity time, be judged as that this touch input is the touch input carried out with felt pen.In addition, in one embodiment of the invention, the above 3 judge that key element is all considered the input judging whether to carry out with felt pen, but, also only can consider that above-mentioned three judge that one or two judgement in key element usually will judge the touch input whether carried out with felt pen.
If judged result is this touch input is in step 320 the input carried out with felt pen, then enters step 330, the input pattern of touch-sensing device 210 is set as pen mode, enter step 350.In step 350, touch input critical range is set as 1.5 π by touch-sensing control module 212.Enter next step 370.In addition, although in step 350 touch input critical range is set as 1.5 π, this value also can be changed to any one value in 1 to 2 π.
If judged result is this touch input is not in step 320 the input carried out with felt pen, then enters step 340, the input pattern of touch-sensing device 210 is set as general modfel, enter step 360.In step 360, touch input critical range is set as 4 π by touch-sensing control module 212.Enter next step 370.
In step 370, touch-sensing control module 212, the benchmark tracking condition of setting touch-sensing device 200.Benchmark is followed the tracks of and is referred to, the initial value of reference current (or voltage) value of the change caused will be changed by static capacity during touch input, the environmental change of consideration touch-sensing device periphery or noise etc., in stability margin (stable margin), reference value is adjusted to below baseline adaptation values, the change of surrounding enviroment or the impact of noise are reduced to minimum technology.In one embodiment of the invention, the baseline adaptation values used in can being followed the tracks of by benchmark according to input pattern sets different.Preferably the baseline adaptation values under pen mode is less than with setting the baseline adaptation values under general modfel.
